What is thermal glazing ?
Thermal glazing, more commonly known as double glazing, provides high insulation performance and lowers the heat transmission coefficient Ug of the entire glazing unit. It therefore has a strong impact on the energy performance of a home.
The difference between single and double glazing is linked to their composition. Here are some explanations of this difference.
Single glazing allows most of the sun’s rays (visible and infrared) to pass through. Its single glazing system also allows any heat that may be emitted inside a dwelling or building to escape. The consequence is a high loss of heat from the home and lower energy savings.
Double glazing consists of two panes of glass with a space between them filled with dehydrated gas. The layer of glass closer to the inside is covered with a heat-reflecting surface to keep the heat inside the room. Double glazing can achieve 0.9 W/m2°K (watt per square metre degree Kelvin) compared to 5 for single glazing!
In addition, other technologies can further improve the insulation of double glazing against external heat: with a solar control coating!
